Bug in ParseState.java?

Hi,

I was looking through ParseState.java and found this method in it.  I
don't know if you have addressed it already, but...:

/* 
 * The lower case part is the same as the upper case part.  I think that

    final String toString(byte raw[], boolean lower) {
	if ( lower ) {
	    // To lower case:
	    for (int i = start; i < end ; i++)
		raw[i] = (((raw[i] >= 'A') && (raw[i] <= 'Z'))
			  ? (byte) (raw[i] - 'A' + 'a')
			  : raw[i]);
	} else {
	    // To upper case:
	    for (int i = start; i < end ; i++)
		raw[i] = (((raw[i] >= 'A') && (raw[i] <= 'Z'))
			  ? (byte) (raw[i] - 'A' + 'a')
			  : raw[i]);
	
	}
	return new String(raw, 0, start, end-start);
    }
